Meter Advice / Promblem

I have some concerns of the accuracy of the meter I’m currently using. Having performed some tests over the last couple of days I find the wavesense Jazz is consistently giving higher results of as much as 4.mml/ml! As I’ve been using this meter as the main machine, it explains why I’ve had a couple of hypos over the last week.
The meter I’ve been comparing with are the AccuCheck Nano, and a ‘True result’ (don’t like the meter, but that is another story), and Bay Liner which I would hope is the most accurate of all, as I’ve borrowed it from my paramedic partner. All with the same sample of blood, after washing hands etc. I’ve tried to be as scientific and accurate as possible.
I know that meters /strips can be up 10-20% -/+ accurate, but 4 whole mol is a hell of a lot and has to be out of that range. I’m seeing my doctor later today and will discuss this with them, but got a feeling I’m going to have a fight on my hands. (Not sure what I want the result of that conversation to be)
Do you think is wavesense faulty or just a poor meter?

I can't comment directly re your meter and the ones you are comparing it to, but it does sound like it is faulty. Is there a control sample you could test with - Some companies will send you a control sample free so you can test it, and if the results are out of the normal range then they will send you a new one. = as they want the custom from the NHS.

As you quite rightly point out - they all have a range, and non are truly accurate, even the one used by your paramedic partner - they are only to give an indication, and so the 10-20% range is considered acceptable.

Do the other meters you test against all give a result within a similar range, whilst the Jazz is way higher - if so, it sounds like the Jazz is faulty.

Thanks Simon, just the confirmation I needed
